What is the favorite Lisp platform of the moment?
Say you want to integrate with a Linux-Python-AWS shop if that matters. Any external API -- crypto, aws, json -- we'd love to have it in Lisp natively, but whatever we'll wrap the c lib via FFI.
- SBCL as the compiler
- Emacs and SLIME for the editor/IDE
- Quicklisp for package management
- SBCL’s built-in static executable compiler for deployment, or sometimes docker if that happens to be more convenient
- Practical Common Lisp for training; Paradigms in AI Programming for taking a trained Lisp programmer “minting” a better Lisp programmer
For individual libraries, there are too many to name. I like yason for JSON, Hunchentoot for web servers, Postmodern for Postgres/SQL, cl-sqlite for SQLite, fiasco for testing, etc.
Integration is easy because there's no integration. You can just call whatever functions you'd normally call.
Common Lisp, which is what I generally mean when I say “Lisp” can be embedded in any language that speaks C with Embeddable Common Lisp.
It isn't, though, and the experience I have had with languages like that is usually no different than the one I have with python or lua - but with the added benefit of being able to at least use macros.
